Pronunciation: [pɛlˈe͡ɪd͡ʒə] (IPA) 
The correct spelling of the word "Pellagia" can be confusing for some. It is pronounced as /pɛˈleɪdʒə/ with four syllables. In phonetic terms, it begins with a short "eh" sound, followed by a long "ay" sound. The third syllable starts with a "j" sound and ends with a short "uh" sound.

Pellagia refers to a medical condition known as pellagra, which is a systemic disorder caused by a deficiency of niacin (vitamin B3) in the diet. This condition typically occurs in regions where people’s diet mainly consists of maize or corn, which is deficient in niacin. Pellagra is characterized by the "4 Ds": dermatitis, diarrhea, dementia, and death if left untreated.
The dermatitis resulting from pellagra is often presented as a characteristic rash, primarily affecting areas of the skin exposed to sunlight. It is accompanied by other symptoms such as photosensitivity, itching, and skin discoloration. Diarrhea, another hallmark of pellagra, is persistent and contributes to malnutrition and weight loss.
Moreover, the neurological manifestations of pellagra include dementia, confusion, depression, irritability, and anxiety. If the condition is not diagnosed and treated promptly, it can progress to severe mental impairment and even death. Therefore, early detection is crucial for a positive prognosis.
The treatment for pellagra usually involves the administration of niacin supplements, along with changes in the diet to ensure an adequate intake of niacin-rich foods such as meat, fish, peanuts, and whole grains. Improvement in symptoms is typically observed within a few weeks of initiating treatment.
Overall, pellagia, or pellagra, is a serious nutritional deficiency disorder characterized by dermatitis, diarrhea, dementia, and potential fatality, caused by inadequate consumption of niacin.
The etymology of the word "Pellagia" can be traced back to the Italian word "pellegrina" or "pellegrino", which means "pilgrim" or "stranger". In Italian folklore, "Pellagia" refers to a female pilgrim or wanderer.
